Hot Rolled Pickled Coil (HRP coil) refers to a type of steel coil that has undergone a specific pickling process after hot rolling. The pickling process removes the mill scale and oxide layers from the steel surface, leaving it with a smooth and clean appearance. The steel coil is left with a matte or slightly rough texture. What's more, the pickling process improves the corrosion resistance of the steel coil by removing the surface impurities. However, HRP coils are still susceptible to corrosion and require further protection, such as applying a protective coating or using them as a substrate for further processing.
